Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00455 - 0.02896), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.4 ±0.2 se; based on size and trophs of closest relatives

Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (K=0.5).

Fishing Vulnerability (Ref. 59153): Low vulnerability (24 of 100).
